摘要:

采用吸水率测试EIS、附着力测试SEM、FT-IR等方法，对比研究常压-静态环境 (0.1 MPa-0 m/s)、流体流动环境 (0.1 MPa-4 m/s)、高静水压力环境 (10 MPa-0 m/s) 和压力-流速耦合环境 (10 MPa-4 m/s) 下环氧玻璃鳞片涂层的失效行为和机制。实验结果表明，耦合环境下，填料与涂层基体间的界面结合被显著削弱，涂层的物理结构发生严重破环，腐蚀介质在涂层中加速扩散，并在涂层缺陷和涂层/金属界面处大量聚集，导致涂层吸水率大幅上升，力学性能显著下降，附着力迅速丧失，发生大面积鼓泡，快速失效。

Abstract：

The failure behavior of epoxy glass flake coating in artificial seawater of various states, namely atmospheric static (0.1 MPa-0 m/s), atmospheric flowing (0.1 MPa-4 m/s), high hydrostatic pressure (10 MPa-0 m/s) and pressured-flowing (10 MPa-4 m/s) was studied by means of water absorption test, EIS, adhesion test, SEM, FT-IR, etc. The results indicated that, under the action of pressured-flowing artificial seawater, the interfacial bonding strength between pigments with the coating matrix may be significantly weakened, the structure of the coating is severely damaged, which promotes the diffusion of corrosive media in the coating, and in consequence, a large amount of water accumulates in coating defects and the interface of coating/metal, which result in significant increase in the water absorption rate and severe decrease in mechanical properties, as well as in rapid loss of coating adhesion and bubbling of the coating, as a result, the coating fails quickly. Finally, the failure mechanism of organic coatings induced by pressured-flowing artificial seawater was also discussed.

Key words： pressure-flow velocity coupling environment epoxy glass flake coating diffusion EIS interface physical structure bubbling failure
